Prove that the charge induced does not depend on the rate of change of magnetic flux.

Assertion (A): Whenever the magnetic flux linked with a closed coil changes there will be an induced emf as well as an induced current. Reason (R ) : Accroding to Faraday, the induced emf is inversely proportional to the rate of change of magnetic flux linked with a coil.

Statement-1 : The induced e.m.f. and current will be same in two identical loops of copper and aluminium, when rotated with same speed in the same magnetic field. Statement-2 : Induced e.m.f. is proportional to rate of change of magnetic field while induced current depends on resistance of wire.

The resistance of a coil is 5 ohm and a current of 0.2A is induced in it due to a varying magnetic field. The rate of change of magnetic flux in it will be-

The induced e.m.f. in a coil does not depend on

Assertion: Magnetic field B (shown inwards) varies with time t as shown. At time to induced current in the loop is clockwise Reason : If rate of change of magnetic flux from a coil is constant, charge should flow in the coil at a constant rate.

Asseration:The induced e.m.f. and curent will be same in two identical loops of copper and aluminium, when rotated with same speed in the same magnetic field. Reason:Induced e.m.f. is proportional to rate of change of magnetic field while induced current depends on resistance of wire.
